摘要： 正在设计建设中的港珠澳大桥珠海连接线工程拱北隧道总长2741 m，采用双层明挖+局部双层暗挖双向六车道的隧道形式，隧道施工采用了先岛后隧明挖法和大断面、长距离、多管节、曲线管幕顶进方法。隧道具有断面大、埋深小、地层软弱、地下水丰富、周边环境敏感等特点，是目前我国已建及在建的水下公路隧道中环境条件最复杂、施工难度最大、综合技术含量最高的隧道工程之一。

Abstract: The Gongbei Tunnel has a total length of 2,741 meters and is part of the HongKongZhuhaiMacau Bridge Connector Project. The tunnel has a total of six traffic lanes in both directions. The tunnel has the characteristics of large crosssections, shallow embedment, soft soil environment, rich groundwater and the sensitive environment. The construction of this tunnel is the known most complicated geological environment, most difficult in construction and highest technological requirement among all tunnels that under construction in China. Its construction utilizes both cut & cover and partial tunneling methods. The tunneling construction utilizes constructing island first, then cut and cover as well as long distance tunneling, multiple points and curvature jacking methods.

Key words: Underwater Tunnel Jacking, Extra Large Tunnel Cross Section, Cut and Cover of Shallow Tunnels
